Napoleon the Third, Emperor of France and nephew of the great Napoleon, boasted that in spite of all his royal duties he could remember the name of every person he met.

His technique? Simple. If he didn’t hear the name distinctly, he said, “So sorry. I didn’t get the name clearly.” Then, if it was an unusual name, he would say, “How is it spelled?”

During the conversation, he took the trouble to repeat the name several times, and tried to associate it in his mind with the person’s features, expression and general appearance.

If the person was someone of importance, Napoleon went to even further pains. As soon as His Royal Highness was alone, he wrote the name down on a piece of paper, looked at it, concentrated on it, fixed it securely in his mind, and then tore up the paper. In this way, he gained an eye impression of the name as well as an ear impression.
